HTTP::MultiPartParser - HTTP MultiPart Parser
SYNOPSIS
$parser = HTTP::MultiPartParser->new(
boundary => $boundary,
on_header => $on_header,

);
while ($octets = read_octets_from_body()) {
$parser->parse($octets);
}
$parser->finish;
DESCRIPTION
This class provides a low-level API for processing MultiPart MIME data
streams conforming to MultiPart types as defined in RFC 2616

$parser = HTTP::MultiPartParser->new( %attributes );
This constructor returns a instance of "HTTP::MultiPartParser". Valid
attributes inculde:
* "boundary" (Mandatory)

Content-Type header field. The *boundary* parameter value consist of
a restricted set of characters as defined in RFC 2046

"+" / "_" / "," / "-" / "." /
"/" / ":" / "=" / "?"
* "on_header" (Mandatory)
on_header => $callback->($header)
This callback will be invoked when the header of a part has
successfully been received. The callback will only be invoked once
for each part.
* "on_header_as"
on_header_as => 'unparsed' | 'lines'
Defines the $header value for the "on_header" callback.
* "unparsed"
Callback invoked with an octet string containing the unparsed

on_error => $callback->($message)
This callback will be invoked anytime an error occurs in the parser.
After receiving an error the parser is no longer useful in its
current state.
* "max_preamble_size"
max_preamble_size => 32768
* "max_header_size"
max_header_size => 32768

$parser->parse($octets);
Parses the given octets.
finish
$parser->finish;
Finish the parsing.
reset
$parser->reset;
